For a few fortnights I've been getting a lot of good results on yahoo. Is it just me? Is anyone else out here experiencing increased yahoo traffic? If so, the company is surging, clearly.

No Yahoo is not surging and likely won't for a long time if ever. You likely just got some good rankings. You should have Google Analytics installed so that you can see exactly where your traffic is coming from.

You might have a good ranking on Yahoo for specific keyword which is more in demand. I haven't seen this kind of traffic increased from yahoo.

I don know. I personally believe Yahoo is really working hard to get back in the race and will sure do in a short period of time.

Yahoo ! is really tweaking its results & really working upon its algorithm.

Possible that one of your keywords got a good ranking in yahoo that's why you got good traffic.
